Answer:

110z+12 /40

Step-by-step explanation:

To answer the question above,one has to be very much careful to prevent error and any error will surely give a wrong answer and ensure that no step is missed

Back to the given question

3/4 (z+2/5)+2z

Start solving by opening the bracket

That is,3/4(z+2/5)

3z/4 + 3/10

To the remaining part

3z/4+3/10+2z

Find the LCM and the LCM is 40

30z+12+80z /40

Collect like terms

30z+80z+12 /40

110z+12 /40

Which means that the given question cannot be solved further

Therefore the final answer is 110z+12 /40
